Hello I'd used Catalyst Control Centre for overclock it. I made my core 900Mhz and memory: 1300 Mhz. and I want ask you there is Fan Speed option there with a tick for manualy % raising. I have't tick that and is default. It's ok or I must made it manualy? and what speed I must raising it? Like yours 35%? But when I playing ultra setting havy gamesIt will be ok with the manualy 35% or better use untick options that give you auto raising a think? Thank you
